I agree that it looks good. My one question would be if you have enough material in your existing headstock to replicate it. It looks fairly high on one side.
You might want to use a pencil to show the wood and would not be there when you shape your head stock. Take a good look at it before you cut. If you like it, great!
The trick, I think is to get something that you think looks as good as the traditional. I think the reason that fender and Gibson had headstocks have remained so common, is that they're pleasing to the eye. Balanced. You want to see if you can develop something that is as good with the material that you have.
I have also gone both ways with this, sometimes cutting sometimes leaving the traditional. I also vary how I paint. I usually now model the headstock on the computer. That way I can try different things before I actually do any cutting or painting. And I can spend a while looking at it before I decide what I like or don't like.
As I read this it looks like I'm giving a formula for procrastination. Maybe therein lies the reason that my builds seem to take so long...
